"Essuie-glace de véhicule automobile""Motor vehicle wiper"

La présente invention concerne un essuie-glace de véhicule automobile. L'invention concerne plus particulièrement un essuie-glace du type dans lequel un capot est destiné à recouvrir intégralement une tête d'entraînement en balayage alterné d'un balai d'essuie-glace par rapport à laquelle il est monté articulé, autour d'un axe transversal, entre une position de service et une position relevée, du type dans lequel le capot comporte deux flancs latéraux longitudinaux réunis par un dos transversal qui comporte une partie longitudinale supérieure et, au niveau de son extrémité arrière, une partie recourbée vers le bas.The present invention relates to a motor vehicle windscreen wiper. The invention relates more particularly to a wiper of the type in which a cover is intended to completely cover a drive head in alternating wiping of a wiper blade with respect to which it is mounted articulated, around a transverse axis, between a service position and a raised position, of the type in which the cover has two longitudinal lateral flanks joined by a transverse back which has an upper longitudinal part and, at its rear end, a part bent towards the low.

On connaît de nombreux exemples d'une telle conception d'un essuie-glace dans lesquels, afin d'améliorer l'aspect de la partie longitudinale arrière de l'essuie-glace qui est montée sur l'extrémité libre supérieure d'un arbre d'entraînement, et afin de protéger les éléments de fixation de l'essuie-glace sur l'arbre d'entraînement, il est prévu un agencement de capot d'habillage selon la conception mentionnée ci- dessus. Selon une première conception, le capot d'habillage et de protection peut être une pièce rapportée directement sur le corps de la tête d'entraînement et qui est indépendante des autres composants de l'essuie- glace.Numerous examples are known of such a design of a wiper in which, in order to improve the appearance of the rear longitudinal part of the wiper which is mounted on the upper free end of a shaft drive, and in order to protect the fastening elements of the wiper on the drive shaft, there is provided a cover hood arrangement according to the above-mentioned design. According to a first design, the covering and protection cover can be an insert directly on the body of the drive head and which is independent of the other components of the wiper.

Le capot d'habillage peut être monté mobile par rapport à la partie longitudinale arrière du bras d'essuie-glace qui est montée articulée sur la tête d'entraînement autour d'un axe transversal.The cover can be mounted movable relative to the rear longitudinal part of the wiper arm which is hinged on the drive head about a transverse axis.

Selon encore une autre conception, le capot peut être constitué par la partie longitudinale arrière du bras d'essuie-glace proprement dit qui est conformée en un carter et qui est articulée sur la tête d'entraînement autour d'un axe transversal agencé à proximité de l'extrémité longitudinale arrière du bras d'essuie-glace.According to yet another design, the cover can be constituted by the rear longitudinal part of the wiper arm proper which is shaped into a casing and which is articulated on the drive head around a transverse axis arranged nearby. from the rear longitudinal end of the wiper arm.

Quelle que soit la conception, il est souhaitable, au moins après un premier montage de l'essuie-glace sur le véhicule, ou en vue de permettre ce premier montage, de pouvoir accéder aux moyens de fixation de la tête d'entraînement sur l'extrémité de l'arbre d'entraînement, et ceci sans nécessiter de démontage des différents composants de l'essuie- glace, et notamment du bras d'essuie-glace, qui est en général sollicité par un ressort d'essuyage dont le montage et le démontage sont particulièrement complexes. Dans ce but, l'invention propose un essuie-glace du type mentionné précédemment, caractérisé en ce que le dos transversal du capot comporte une ouverture donnant accès à des moyens de fixation de la tête d'entraînement sur l'extrémité d'un arbre d'entraînement en balayage alterné, et en ce qu'il est prévu un couvercle, de contour complémentaire de celui de l'ouverture, qui est monté articulé sur le capot entre une position fermée de service dans laquelle il obture l'ouverture et une position ouverte relevée dans laquelle l'ouverture est dégagée.Whatever the design, it is desirable, at least after a first assembly of the wiper on the vehicle, or in order to allow this first assembly, to be able to access the means for fixing the drive head to the end of the drive shaft, and this without requiring disassembly of the various components of the wiper, and in particular of the wiper arm, which is generally stressed by a wiper spring, the mounting of which and disassembly are particularly complex. For this purpose, the invention provides a wiper of the type mentioned above, characterized in that the transverse back of the hood has an opening giving access to means for fixing the drive head to the end of a shaft drive in alternating scanning, and in that there is provided a cover, of contour complementary to that of the opening, which is hinged mounted on the cover between a closed service position in which it closes the opening and a open position raised in which the opening is cleared.

On a représenté sur les figures une partie longitudinale arrière en forme de capot 1 0 qui appartient ici à un bras d'essuie-glace, non représenté en détail, dont l'extrémité longitudinale avant (non représentée) porte en général un balai d'essuyage d'une vitre à essuyer. Conformément aux enseignements de l'invention, la partie arrière supérieure du capot 10 est associée à un couvercle articulé 12 qui est prévu pour obturer une ouverture 14 du capot permettant d'accéder aux moyens de fixation d'une tête d'entraînement (non représentée) de l'essuie-glace sur un arbre (non représenté) d'entraînement en rotation en balayage alterné.There is shown in the figures a rear longitudinal part in the form of a cover 1 0 which here belongs to a wiper arm, not shown in detail, the front longitudinal end of which (not shown) generally carries a wiper blade. wiping a window to wipe. In accordance with the teachings of the invention, the upper rear part of the cover 10 is associated with an articulated cover 12 which is provided for closing an opening 14 in the cover allowing access to the means for fixing a drive head (not shown ) of the windscreen wiper on a shaft (not shown) for rotationally rotating alternating sweep.

Selon une conception générale connue, le capot 10 est constitué pour l'essentiel par deux flancs latéraux longitudinaux 16 qui s'étendent parallèlement dans des plans verticaux et qui sont réunis par un dos transversal 1 8. Selon une conception connue, le capot 10 est une pièce moulée, par exemple en matière plastique, et il comporte au voisinage de son extrémité longitudinale arrière, c'est-à-dire à gauche en considérant les figures 2 et 3, un axe transversal 20 d'articulation du capot sur la tête d'entraînement qui relie entre elles les faces internes en vis-à-vis 22 des flancs latéraux 16 du capot 1 0.According to a known general design, the cover 10 consists essentially of two longitudinal lateral flanks 16 which extend parallel in vertical planes and which are joined by a transverse back 1 8. According to a known design, the cover 10 is a molded part, for example made of plastic, and it comprises, in the vicinity of its rear longitudinal end, that is to say on the left when considering FIGS. 2 and 3, a transverse axis 20 of articulation of the cover on the head drive which interconnects the internal faces facing 22 of the lateral flanks 16 of the cover 1 0.

Le dos transversal 1 8 est constitué pour l'essentiel par une partie longitudinale supérieure 24 qui s'étend dans un plan sensiblement horizontal et qui se prolonge longitudinalement vers l'arrière par une partie d'extrémité arrière 26 recourbée vers le bas qui rejoint les flancs latéraux 16 de manière que le carter formant capot 10 soit délimité verticalement vers le bas par un bord inférieur continu 28 situé dans un plan horizontal parallèle au plan général de la partie longitudinale supérieure 24 du dos 18. Comme on peut le voir notamment aux figures 1 à 3, la partie supérieure et longitudinale arrière du capot 1 0 est "découpée" par une ouverture 14, réalisée venue de matière par moulage, qui est délimitée longitudinalement par un bord transversal avant 30 et par un bord transversal arrière 32. Le bord transversal avant 30 est formé dans la partie longitudinale supérieure 24 du dos 1 8 tandis que le bord transversal arrière 32, qui est décalé verticalement vers le bas par rapport au bord transversal avant 30, est formé dans la partie arrière recourbée vers le bas 26. L'ouverture 14 est aussi délimitée latéralement par deux bords longitudinaux 34 qui sont formés dans les flancs latéraux 16.The transverse back 1 8 essentially consists of an upper longitudinal part 24 which extends in a substantially horizontal plane and which extends longitudinally towards the rear by a rear end part 26 curved downwards which joins the lateral flanks 16 so that the casing forming the cover 10 is delimited vertically downwards by a continuous lower edge 28 situated in a horizontal plane parallel to the general plane of the upper longitudinal part 24 of the back 18. As can be seen in particular in FIGS. 1 to 3, the upper and longitudinal rear part of the cover 1 0 is "cut" by an opening 14, produced integrally by molding, which is delimited longitudinally by a front transverse edge 30 and by a rear transverse edge 32. The front transverse edge 30 is formed in the upper longitudinal part 24 of the back 18 while the rear transverse edge 32, which is vertically offset downward relative to the front transverse edge 30, is formed in the rear part curved downwards 26. The opening 14 is also delimited laterally by two longitudinal edges 34 which are formed in the lateral flanks 16.

Comme on peut le voir aux figures 1 à 4, le couvercle 12, qui est aussi une pièce moulée par exemple en matière plastique, est une pièce complémentaire de la forme et du profil général de la partie d'extrémité arrière du capot 10 et son contour inférieur est notamment complémentaire du contour de l'ouverture 14 constituée par les bords 30 à 34.As can be seen in Figures 1 to 4, the cover 12, which is also a molded piece for example of plastic, is a piece complementary to the shape and general profile of the rear end part of the cover 10 and its lower contour is in particular complementary to the contour of the opening 14 constituted by the edges 30 to 34.

Ainsi, le couvercle 12 présente une forme de coque constituée par un dos supérieur 36 qui comporte une partie avant 38 d'orientation longitudinale et horizontale et une partie arrière recourbée vers le bas 40, et qui réunit deux flancs longitudinaux 42.Thus, the cover 12 has a shell shape constituted by an upper back 36 which has a front part 38 of longitudinal and horizontal orientation and a rear part curved downwards 40, and which joins two longitudinal sides 42.

Le contour inférieur du couvercle 12 est délimité par un bord transversal avant 44, un bord transversal arrière 46 et par deux bords longitudinaux 48.The lower contour of the cover 12 is delimited by a front transverse edge 44, a rear transverse edge 46 and by two longitudinal edges 48.

Comme on peut le voir à la figure 3, en position fermée de service, et du fait de la complémentarité du contour inférieur du couvercle 12 et du contour de l'ouverture 14, le couvercle 12 complète parfaitement le capot 1 0 qui se présente avec un profil homogène et continu.As can be seen in Figure 3, in the closed service position, and due to the complementarity of the lower outline of the cover 12 and the outline of the opening 14, the cover 12 perfectly completes the cover 1 0 which comes with a homogeneous and continuous profile.

Conformément aux enseignements de l'invention, le couvercle 12 est monté articulé sur la capot 1 0 entre une position horizontale fermée de service, illustrée à la figure 3, et une position ouverte relevée illustrée à la figure 5.In accordance with the teachings of the invention, the cover 12 is hinged on the cover 1 0 between a closed horizontal service position, illustrated in FIG. 3, and a raised open position illustrated in FIG. 5.

Dans l'exemple illustré sur les figures, le couvercle 12 est articulé par rapport au capot 1 0 autour d'un axe horizontal d'orientation transversale A1 qui est agencé au voisinage du bord transversal avant 30 de l'ouverture 14 et qui est décalé longitudinalement vers l'avant par rapport à ce dernier.In the example illustrated in the figures, the cover 12 is articulated relative to the cover 1 0 about a horizontal axis of transverse orientation A1 which is arranged in the vicinity of the front transverse edge 30 of the opening 14 and which is longitudinally offset forward relative to the latter.

Afin d'obtenir cette articulation, le couvercle 12 comporte une patte 50 d'articulation. La patte 50 est réalisée venue de matière par moulage avec le couvercle 12 et elle s'étend globalement longitudinalement vers l'avant à partir du bord transversal avant 44 du couvercle 12.In order to obtain this articulation, the cover 12 includes a hinge tab 50. The tab 50 is produced integrally by molding with the cover 12 and it extends generally longitudinally forward from the front transverse edge 44 of the cover 12.

La patte 50 présente un profil incurvé en arc de cercle et elle est délimitée par une face supérieure 52 en arc de cylindre concave et par une face inférieure parallèle en arc de cylindre convexe 54. Ces deux surfaces en arc de cylindre sont centrées autour d'un axe transversal A2 qui est décalé longitudinalement vers l'avant par rapport au bord transversal avantThe tab 50 has a curved profile in an arc of a circle and it is delimited by an upper face 52 in an arc of a concave cylinder and by a parallel lower face in an arc of a convex cylinder 54. These two surfaces in arc of a cylinder are centered around a transverse axis A2 which is offset longitudinally forward with respect to the front transverse edge

44 et qui, en position montée du couvercle 12 sur le capot 10, est confondu avec l'axe A1 d'articulation et de pivotement du couvercle 12 par rapport au capot 1 0.44 and which, in the mounted position of the cover 12 on the cover 10, coincides with the axis A1 of articulation and pivoting of the cover 12 relative to the cover 1 0.

La patte d'articulation 50 est renforcée par deux nervures longitudinales de renfort 56 qui s'étendent verticalement vers le bas à partir des bords longitudinaux latéraux de la patte incurvée d'articulationThe articulation tab 50 is reinforced by two longitudinal reinforcing ribs 56 which extend vertically downwards from the lateral longitudinal edges of the curved articulation tab

50. Afin d'assurer un mouvement de pivotement du couvercle 12 autour de l'axe commun A1 , A2, la patte incurvée d'articulation 50 est guidée en coulissement dans une fente 60 du capot 10.50. In order to ensure a pivoting movement of the cover 12 around the common axis A1, A2, the curved articulation tab 50 is guided in sliding in a slot 60 of the cover 10.

Plus précisément, la fente 60 est formée dans la partie longitudinale supérieure 24 du dos 18 et elle est délimitée d'une part par le bord transversal avant 30 de l'ouverture 14 et d'autre part par une portion de bord transversal arrière parallèle 62 qui appartient à une entretoise transversale 64 du capot 10.More specifically, the slot 60 is formed in the upper longitudinal part 24 of the back 18 and it is delimited on the one hand by the front transverse edge 30 of the opening 14 and on the other hand by a portion of parallel rear transverse edge 62 which belongs to a transverse spacer 64 of the cover 10.

Les deux bords en vis-à-vis 30 et 62 qui délimitent la fente 60 sont, comme on peut le voir plus particulièrement à la figure 5, de profil en arc de cylindre, c'est-à-dire que le bord 30 est convexe tandis que le bordThe two facing edges 30 and 62 which delimit the slot 60 are, as can be seen more particularly in FIG. 5, in profile in the shape of an arc of a cylinder, that is to say that the edge 30 is convex while the edge

60 est concave, de manière à délimiter une fente profilée à profil en arc de cercle selon des rayons complémentaires de ceux des surfaces en arc de cylindre 52 et 54 de la patte d'articulation 50.60 is concave, so as to delimit a profiled slot with a circular arc profile according to radii complementary to those of the cylindrical arc surfaces 52 and 54 of the articulation tab 50.

La traverse 64 est une pièce, réalisée venue de matière par moulage avec le capot 10, qui présente une forme de "visière" qui s'étend en partie dans l'ouverture 14 en arrière du bord transversal avant 30 et qui est décalée verticalement vers le bas par rapport à la partie longitudinale supérieure 24 du dos 18. La traverse 64 est constituée pour l'essentiel par une plaque supérieure mince 66 qui s'étend parallèlement à la partie 24 du dos 18 et qui est reliée au capot 1 0 par deux ailes latérales longitudinales 68. Dans sa partie médiane, la plaque principale horizontale 66 de la traverse 64 comporte deux fentes parallèles 70 qui délimitent entre elles une languette 72 qui constitue une poutre déformable élastiquement, encastrée par son extrémité longitudinale arrière, dont l'extrémité libre avant comporte un tronçon du bord 62 de la fente 60 qui coopère avec la partie médiane de la surface inférieure en arc de cylindre convexe 54 de la patte d'articulation 50.The crosspiece 64 is a part, produced integrally by molding with the cover 10, which has a form of "visor" which extends in part in the opening 14 behind the front transverse edge 30 and which is offset vertically towards the bottom relative to the upper longitudinal part 24 of the back 18. The crosspiece 64 is essentially constituted by a thin upper plate 66 which extends parallel to the part 24 of the back 18 and which is connected to the cover 1 0 by two longitudinal side wings 68. In its middle part, the main plate horizontal 66 of the crosspiece 64 comprises two parallel slots 70 which delimit between them a tongue 72 which constitutes an elastically deformable beam, embedded by its rear longitudinal end, the front free end of which comprises a section of the edge 62 of the cooperating slot 60 with the middle part of the lower surface in the shape of a convex cylinder arc 54 of the hinge tab 50.

Outre la conformation de la fente 60 avec ses bords 30 et 62, le guidage en pivotement de la patte d'articulation 50 autour de l'axe commun A1 , A2 est complété par quatre joues 74 de guidage qui sont des joues qui s'étendent dans des plans verticaux et longitudinaux à l'intérieur du capot 10, à partir de la face interne 25 de la partie longitudinale supérieure 24 du dos 18, comme on peut le voir notamment à la figure 1 0.In addition to the conformation of the slot 60 with its edges 30 and 62, the pivoting guide of the hinge tab 50 around the common axis A1, A2 is completed by four guide cheeks 74 which are cheeks which extend in vertical and longitudinal planes inside the cover 10, from the internal face 25 of the upper longitudinal part 24 of the back 18, as can be seen in particular in FIG. 1 0.

Les quatre joues sont parallèles et sont agencées au voisinage du bord transversal avant 30 de l'ouverture 14 et chacune d'elles est délimitée par un bord longitudinal inférieur 76 en arc de cercle centré sur l'axe A1 .The four cheeks are parallel and are arranged in the vicinity of the front transverse edge 30 of the opening 14 and each of them is delimited by a lower longitudinal edge 76 in an arc centered on the axis A1.

Les quatre bords 76 constituent ainsi globalement une surface, convexe en arc de cylindre, de guidage de la patte d'articulation 50 qui coopère avec la face supérieure en arc de cylindre concave 52 de la patte 50. La largeur de la fente 60, c'est-à-dire la distance séparant normalement les bords 30 et 62, est sensiblement égale à l'épaisseur moyenne "e" (voir figure 5) de la partie principale de la patte d'articulation 50.The four edges 76 thus generally constitute a surface, convex in the shape of an arc of a cylinder, for guiding the articulation tab 50 which cooperates with the upper surface in the form of a concave cylinder arc 52 of the tab 50. The width of the slot 60, c that is to say the distance normally separating the edges 30 and 62, is substantially equal to the average thickness "e" (see FIG. 5) of the main part of the hinge tab 50.

Toutefois, comme on peut le voir à la figure 5, la partie d'extrémité libre avant 78 de la patte d'articulation 50 présente une surépaisseur de manière à constituer un frein par coincement qui permet de maintenir le couvercle 12 dans sa position ouverte relevée illustrée à la figure 5 sans que celui retombe de manière intempestive vers sa position fermée horizontale de la figure 3. Outre la partie plus épaisse 78, il est prévu un cran 79 dans la face inférieure 54 pour éviter l'échappement accidentel du couvercle 12 au cas où celui-ci serait sollicité en rotation autour de l'axe A1 , dans le sens horaire, au-delà de sa position relevée illustrée à la figure 5. L'engagement de la partie plus épaisse 78 de la fente 60 est rendu possible grâce à la capacité de la languette 62 à se déformer élastiquement à la manière d'une poutre élastique.However, as can be seen in FIG. 5, the free front end part 78 of the articulation tab 50 has an extra thickness so as to constitute a wedging brake which makes it possible to maintain the cover 12 in its raised open position illustrated in FIG. 5 without the one inadvertently falling back towards its horizontal closed position in FIG. 3. In addition to the thicker part 78, there is a notch 79 in the lower face 54 to prevent accidental escape of the cover 12 at case it would be rotated around the axis A1, clockwise, beyond its raised position illustrated in Figure 5. The engagement of the thicker part 78 of the slot 60 is made possible by the ability of the tongue 62 to deform elastically in the manner of an elastic beam.

De même, le montage par engagement de la patte d'articulation 50 dans la fente 60 est facilité par la conformation en coin 81 de son extrémité libre avant, le profil de coin provoquant l'effacement temporaire de la languette 72 par fléchissement, verticalement vers le bas, en considérant la figure 5, de cette dernière jusqu'à ce qu'elle franchisse le cran 79. Conformément à un autre aspect de l'invention, il est aussi prévu des moyens de verrouillage du couvercle 12 en position fermée de service. Ces moyens de verrouillage sont constitués ici par une série de quatre lames 80 déformables élastiquement qui s'étendent verticalement vers le bas à partir du bord transversal arrière 46. L'extrémité libre inférieure de chaque lame élastique 80 comporte un bec 82, orienté longitudinalement vers l'arrière, qui est susceptible de coopérer par accrochage en dessous d'une nervure horizontale 84 formée dans la face interne 86 de la partie arrière recourbée 26 comme on peut le voir notamment à la figure 6. La conformation arrondie des becs 82 permet leur engagement automatique derrière la nervure 84 par coopération avec une rampe d'introduction 88 ainsi que leur dégagement automatique lorsque l'on désire ouvrir le couvercle 12 en tirant verticalement ce dernier globalement vers le haut pour provoquer son pivotement autour de l'axe A1 . La bonne fermeture étanche du couvercle 12 est complétée, comme on peut le voir notamment à la figure 8, par le profil complémentaire en forme de chicane des bords en vis-à-vis 48 des flancs 42 du couvercle 12 et 34 des flancs 16 du capot 10.Similarly, the mounting by engagement of the hinge tab 50 in the slot 60 is facilitated by the wedge shape 81 of its free front end, the wedge profile causing the temporary erasure of the tongue 72 by bending, vertically towards the bottom, considering FIG. 5, of the latter until it crosses the notch 79. In accordance with another aspect of the invention, there are also provided means for locking the cover 12 in the closed service position. . These locking means consist here of a series of four elastically deformable blades 80 which extend vertically downwards from the rear transverse edge 46. The lower free end of each elastic blade 80 has a spout 82, oriented longitudinally towards the rear, which is capable of cooperating by hooking below a horizontal rib 84 formed in the internal face 86 of the curved rear part 26 as can be seen in particular in FIG. 6. The rounded configuration of the spouts 82 allows them automatic engagement behind the rib 84 by cooperation with an insertion ramp 88 as well as their automatic disengagement when it is desired to open the cover 12 by vertically pulling the latter generally upwards to cause it to pivot about the axis A1. The correct sealing of the cover 12 is completed, as can be seen in particular in FIG. 8, by the complementary baffle-shaped profile of the edges facing 48 of the sides 42 of the cover 12 and 34 of the sides 16 of the cover 10.

Afin d'éviter que les flancs 42 ne s'écartent intempestivement transversalement vers l'extérieur, les faces internes 43 des flancs 42 du couvercle 12 comportent chacune une nervure 90 d'orientation verticale qui fait saillie verticalement vers le bas et qui s'étend en regard de la partie en vis-à-vis de la face interne 22 du flanc 16 associé du capot 10. In order to prevent the sides 42 from inadvertently moving apart transversely towards the outside, the internal faces 43 of the sides 42 of the cover 12 each have a rib 90 of vertical orientation which projects vertically downwards and which extends opposite the part facing the internal face 22 of the sidewall 16 associated with the cover 10.
